【摘要】 针对一个新的四维分段MLS混沌系统,提出了一种特别适合分段混沌系统的同步控制方法。该方法采用直接设计思想,有效地利用了分段混沌系统自身的结构特点,简化了误差系统中分段函数的推导问题,为分段混沌系统的控制提供了一种新思路。同步控制器结构简单,设计中无需推导Lyapunov函数。该方法对于分段L(u|¨)混沌系统等一类分段混沌系统同样适用。通过对MLS混沌系统、分段L(u|¨)混沌系统同步控制的数值仿真,也验证了所提出方法的有效性。更多还原

【Abstract】 For a new four-dimensional piecewise MLS chaotic system,a synchronization control method special adaptive to piecewise chaotic systems is proposed in this paper.Based on the direct-design idea,this method utilizes effectively the structure characteristics of piecewise chaotic systems and simplifies the deducing problem of piecewise-function in error systems.It provides a new thought for controlling piecewise chaotic systems.The synchronization controllers have simple structures and Lyapunov functions need not to be deduced in design process.This method is also useful for a class of piecewise chaotic systems,such as piecewise L(u|¨) chaotic system.The numerical simulations of MLS and piecewise L(u|¨) chaotic systems also show the validity of the proposed method.更多还原
